Subspecies
Often treated as conspecific with Southern White-faced Owl (Ptilopsis granti) but significant differences in DNA and vocal patterns, however, indicate that northern and southern populations specifically distinct. Pale birds in Sudan and dark ones elsewhere have been treated as racially distinct (as margarethae and nigrovertex, respectively), but both considered merely color morphs.
